On the web page it displayed at 3" high in a window about 7" wide, with
a thin line across the bottom and a little dot serving as a position
marker. It either auto-scrolled slowly across through the window or you
could pause the scroll and drag the position marker with your mouse.

I'd like to display and scroll it in this way from my laptop in a
classroom situation. From previous experience I expect I can put it
into a very wide PDF file, and then display and scroll it in Adobe
Reader or Acrobat.

But could anyone give me a little tutorial or pointers to what other
kind of coding or HTML or other software may have been involved in
displaying this on the web site? Is "process_mural" a term of art in
Java or some other kind of coding?
